Hi :

I want to do patents text mining in R.
I need to use the proper nouns of domain ontology to build a dictionary.
Then use the dictionary to analysis my corpus of patent files.
I want to calculate the proper nouns and get the word frequency that appears in each file.

Now I have done the preprocess for the corpus and extract the proper nouns from domain ontology.
But I have no idea how to build a proper nouns dictionary and use the dictionary to analysis my corpus.

The Attachments are my texts, corpus preprocesses and proper nouns.
